Isreali social ticketing firm Evento has secured $750,000 to bolster existing European partnerships and expand its service.

The startup took part in the Microsoft’s Windows Azure Accelerator and since than it has been working on making events go viral, primarily via Facebook.

According to to Sportcal (subscription), private angel investors and a ‘ticketing industry leader’ in Germany invested in shares and the publication reports that these people now own around 50 percent of the business. Who the investors are has not been revealed.

The company stresses that it doesn’t replace existing ticket agencies or sales systems but it creates a Facebook front-end through which it hopes to engage attending fans and promote additional ticket sales.

Fans of events who use the service can see who else is going and where they are sitting. This way they can choose to go along to and sit next to people they know. Evento says the social layer encourages causal fans to join in.

One of Evento’s recent successes has been with the Scarlets Rugby Club in the UK and German basketball team Frankfurt Skyliners. The company says that it is in discussion with many more sports teams to work with them through 2013.

Evento hopes to use some of the funding to expand into the US market to create partnerships with sports teams and ticket agencies.
